To all whom it may concern:

Be it known that I, JAMES G. HARDIE, a citizen of the United States ofAmerica, residing at Canton, in the county of St. Lawrence and State ofNew York, have invented certain new and useful Improvements inPaper-Loading Machines, of which the following is a specification.

The present invention relates to that which may be called a continuous,paperloading machine, because the stock of paper is placed, atintervals, upon this machine, by which it is carried forwardly so thatthe printing press is kept continuously running.

The object of this invention is to furnish mechanism that will permit ofthe stock of paper to be rolled out and placed in such a manner that thestock will constitute one continuous bank of sheets, so shingled outthat the sheets will move forwardly in the most convenient form to bemanually fed to a printing press, or to any other machine to whichsingle sheets are fed.

The accompanying illustrations show the invention mounted upon the feedtable of a printing press, although it is applicable to any other formof machine to which sheets are singly fed.

The invention consists mainly of a suitable frame-work rigidly fastenedto the printing press table, and having a main table mounted upon saidframe-work, upon whichthe stock of paper is placed when rolled out.Around this table and over a main roll belts are passed which carryforwardly the bank of sheets. Between the main table and the press tableis an inclined sub-table around which are passed belts which receive thebank of paper carrying it down to the press table; also around a certainportion of the press table are belts which advance the bank of sheets tothe desired position. Suitably placed beneath the upper table is anelectric motor, suitably belted and geared to the main belt roll. An

electric switch is suitably placed nearthe operator and by operating theswitch the motor is started, which has the effect of moving forwardlythe entire bank of paper.

The invention includes other features of novelty, in addition to thoseabove described, which will be included in the description of theaccompanying drawings and included in the annexed claims.

Figure 1 is a side elevation showing the invention in position, on thetable of a printing press, and the various sets of belts which carry thestock of paper forward; also a stock of paper is shown on the main tablein the rolled-out position. The motor is shown attached to the underside of the main table, in operative connection with the main belt roll,which consists of a flexible belt and then a train of gears; also adiagrammatic view of the electric wiring with the switch in place.Conveniently near the operators chair is shown a tripping mechanism.Fig. 2 is a transverse, sectional view of the invention, on a largerscale than Fig. 1. Fig. 3 is a plan View of the invention showing thebelts passing above the table and around the main belt roll; also theelectric motor shown dotted beneath the table. Fig. 4 is a sideelevation of the gearing. In the accompanying drawings, similar figuresrefer to similarparts throughout.

Fig. 1, A is the rear portion of a printing press showing the impressioncylinder and the table in position; 1 is the side-frame of the loaderand is rigidly fastened upon the press table 2; 3 is the electric motor;4 and 5 are the wires which supply current to the motor; 6 is the switchfor starting and stopping the motor; 7 is a belt passing around a pulleyon the motor and around a pulley 8, on the shaft 9, and between shaft 9and the shaft 10 is a train of gears, shown in Fig. 4. which transmitsmotion to the main roll 11; mounted upon the frame, 1, is the table 12;13 are rolls pivoted to the table; 14: are belts passing around therolls 13, the main roll, 11, and over the tightener roll 15; 16 is aside guide against which is placed thestack of paper 17. Upon the stackof paper rests the idle roll, 18, which is pivotally attached to theframe 1, by the link 19; 20 is a guide to turn the stock of paper in thedirection of the second set of belts 21, which pass around the rolls,22, upon the shaft 23; 24

is a gear, rigid upon the shaft 23, and is in operative connection withthe gear 27, on the shaft 10, through the intermediate pinions 25 and26; 28 is a sub-table placed in the frame-work, 1,0bliquely to the presstable, and are pulleys 1ournaled in the press table; above and below thethese pulleys, are passed the belts 31; 32 is the operators chair; 33 ismeans for tripping the press cylinder.

Fig. 2 shows the friction shoe 34, which normally rests upon the bank ofpaper to supporting the'belts 21; 29 and 30 press table, and aroundprevent the paper sliding down the inclined table 28; the shoe ispivotally attached to the shaft 36, by the link 35.

Fig. 3 is a plan view showing the table 12, the belts 14 passing aroundthe pulleys 13 and the main roll 11, with the idler 18 resting upon thebelts 13 and held in place by the link 19.

Fig. 4 is a side elevation of the gearing. The belt pulley 8 is rigidupon the shaft 9 which carries the pinion 37 which engages the gear 38,upon the shaft 40, which shaft also carries the pinion 39 which is in engagement with the gear 41, upon the shaft 42, which carries the pinion43 in engagement with the gear 27 upon the main roll shaft 10.

Thus, in the operation of my invention, the stock of paper is rolled outand placed upon the belts 14 which are supported by the table 12. Theoperator sits upon the chair 32, and whenever it is desired to moveforwardly the stock of paper to a convenient position to feed the sheetsto the cylinder, the operator presses the knob of the snap-switch 6,which starts the motor 3, which imparts motion to the main roll, 11,through the belt 7 and the accompanying train of gears located betweenthe belt pulley 8 and the main gear 27. This has the effect ofpropelling the belts, 14, which carry the bank of paper forward andunder the idler, 18, and the guide, 20, turns the front edge of the bankof paper forward and upon the second set of belts 21. The belts 21 arepropelled by a train of gears located between the shaft 23 and the gear27. The shoe, 34, rests upon the bank of paper and prevents the paperfrom sliding down the inclined table 28. Upon the shaft, 44, are placedthe pulleys 29 and 45, through which motion is imparted to the belts 31,advancing the bank of paper as may be desired.

I have illustrated and described my invention as mounted upon a printingpress, but I do not wish to be confined to a printing press only butwish to use it on any machine to which it is adapted.

In the construction of my invention, when reduced to practice, it isnecessary that the table 12 be sufficiently elevated above thepress-table to admit of an operator looking across the press and belowthe upper table, to see the side guide on the opposite side of thepresstable; but this construction will locate the main feed-roll 11 inan elevated position, above the press-table; and will, therefore,necessarily require means to carry the bank of paper down the steepincline to the press-table. Various forms of means can be used for thispurpose, and although I have shown a stationary, inclined table withbelts passing around it, I do not confine myself to this particularmeans, but wish to use any suitable means to carry the sheets from themain roll 1.1 to the belts 31 on the press-table.

It is well-known to the trade that sheets of paper must lie flat on thepress-table in order to get the most accurate register. To meet thisneed it is necessary to locate the tape-shaft 44 a predetermineddistance from the impression cylinder, which will locate the shaft 44 sofar back that a steep. incline is made between the main roll and theshaft 44. To properly retard the sheets, in transit,

down this incline, I use shoes which rest upon the stock; the weight ofthe shoes may be varied to suit the grade of paper being fed. The means,however, of carrying and retarding the stock, in transit, may be variedin form without departing from my invention; hence I do not confinemyself to the particular form of means shown, but wish to use whatevermeans will accomplish this end.

Having thus described my invention that which I claim is:

1. The combination in a loading machine of a frame mounted upon aprinting presstable, a table mounted upon said frame, a power-drivenmain roll journaled in said frame, belts passing around said main rolland said table, power-rotated pulleys journaled in said press-table,belts passing around said pulleys above and below said press-table, apower-rotated shaft journaled in said frame, pulleys mounted upon saidshaft, belts passing around said pulleys and around said pulleys in saidpress-table, a suitable member adapted to guide a sheet from the mainroll to said belts.

2. The combination in a loading machine of a frame mounted upon aprinting presstable, a table mounted upon said frame, a power-drivenmain roll journaled in said frame, belts passing around said main rolland said table, power-rotated pulleys journaled in said press-table,belts passing around said pulleys above and below said press-table, atable interposed between said main roll and said printing press-table, apower-rotated shaft journaled in said frame, pulleys mounted upon saidshaft, belts passing around said pulleys and around said interposedtable.
